Mortgage Basics for First-Time Buyers
A mortgage is a long-term loan used to buy a home. The property itself serves as collateral, so the lender can take it if you stop paying.
Because the amounts are large, small differences in rate and terms add up to huge sums.
The main building blocks
- Down payment: the part of the price you pay upfront.
- Principal: the amount you borrow.
- Interest rate: the cost of borrowing.
- Term: commonly 15 to 30 years.
- Amortization: how each payment splits between interest and principal over time.
Fixed vs variable rates
| Feature | Fixed rate | Variable rate |
|---|---|---|
| Payment stability | Same throughout the fixed period | Can rise or fall |
| Starting rate | Often higher | Often lower |
| Best for | Budget certainty | Those who can absorb payment changes |
| Main risk | Paying more if rates fall | Payments rising sharply |
Costs beyond the monthly payment
- Down payment, often 5% to 20% of the price
- Taxes and registration fees
- Valuation and legal fees
- Lender arrangement fees
- Home insurance and property tax
- Maintenance and repairs
A good rule is to budget at least 1% of the property value per year for maintenance.
How much can you afford?
Many lenders prefer that total housing costs stay below about 28% to 35% of your gross income, and total debts below roughly 36% to 43%.
Even if a lender approves more, borrow only what keeps you comfortable if rates or income change.
Steps to prepare
- Check and improve your credit report.
- Save for the down payment and a cash reserve.
- Reduce existing debts.
- Get a mortgage pre-approval to know your range.
- Compare several lenders and mortgage brokers.
- Read every document before signing.
Questions to ask lenders
- What is the APR, not just the headline rate?
- Are there prepayment penalties?
- Can I make extra payments without cost?
- What happens if I lose my income temporarily?
- Is the rate locked, and for how long?
Common first-time mistakes
- Stretching the budget to the maximum.
- Forgetting closing and moving costs.
- Draining all savings for the down payment.
- Taking on new debt before closing.
- Skipping a home inspection.
